Definitions
- the present invention relates to machine collets, and more particularly to a sealing collet for use with tools having a through-hole for the induction of cooling fluid through the tool.
- Coolant is a cutting fluid known to reduce the frictional forces acting on the drill.
- the fluid must have the thermal capability of removing heat generated by the tool and, secondly, the fluid must reach the cutting area or working surfaces of the tool.
- the collet holding the drill must be sealed to allow the coolant to flow to the cutting edge of the drill at a relatively high pressure. If the collet is not adequately sealed, the coolant will leak from around the tool holder cone and the tool holder nut and will not reach the cutting edge with adequate pressure and flow.
- Conventional sealing collets are commercially available, such as the ER-COOLITTM Collet manufactured by Engineers Tool Manufacturing Company, Limited, of Israel and sold through GTE Valenite Corporation of Troy, Mich.
- Another example of conventional sealing collets are the Sealing Collets sold by Rego-Fix Tool Corporation of Indianapolis, Ind.
- the conventional sealing collets such as the type mentioned, relate to the commonly known split steel type collets.
- the Jacobs® Chuck Manufacturing Company manufactures and markets a well known Rubber-Flex® Collet of the type having a plurality of individual gripping members held in position and equally spaced about a common axis.
- the spaces between the gripping members is filled with an adherent resilient material, such as rubber or rubber composition.
- the gripping members have perforations therethrough so that the resilient material not only fills the space between the gripping members but also passes through the perforations forming a plurality of longitudinally spaced continuous angular rings which hold the gripping members in a desired relative position.
- Applicant has, with the present invention, configured a Rubber-Flex® type collet as a sealing collet which has proven to be far superior to conventional sealing collets.
- Another object of the present invention is to provide a sealing collet of the type having individual gripping members molded in resilient rubber-like material.
- Yet another object of the present invention is to provide a sealing collet which is relatively inexpensive to manufacture.
- a sealing collet for use with tools, particularly drills, having a through-hole defined therein for the induction of coolant fluid to the working surfaces or cutting edges of the tool.
- the collet comprises a plurality of independent gripping jaws or blades longitudinally disposed about a common centerline axis.
- the gripping jaws have an exposed inner face parallel to the centerline axis of the collet and define an inner diameter of the collet through which the shaft of the tool or drill is inserted.
- the gripping jaws have an angled exposed outer face whereby the plurality of gripping jaws forms a conical outer surface of the collet.
- the conical outer surface of the collet is compatible with a matching conical receiving surface of a conventional toolholder.
- Resilient material such as rubber or rubber composition, is disposed between each of the gripping jaws and holds the gripping jaws in a predetermined longitudinally and angularly spaced relation about the centerline axis.
- a continuous outer diameter seal is disposed circumferentially about the conical outer surface of the collet.
- the outer diameter seal is formed integral with the resilient material.
- a continuous inner diameter seal is disposed circumferentially within the inner diameter of the collet and is also formed integral with the resilient material.
- the outer diameter seal is disposed generally near the back end of the collet in relation to the collet within a toolholder and comprises a double lip seal. the extreme front end of the collet in relation to the collet within a toolholder.
- the resilient material is essentially flush with the outer faces of the gripping jaws so that the outer diameter of the collet is essentially smooth. It is further preferred to define compression recesses within the resilient material between each gripping member or jaw.
- the sealing collet may require only one seal instead of both an inner diameter and outer diameter seal.
- the sealing collet contain either an inner diameter seal or an outer diameter seal.
- the inner diameter and outer diameter seals are formed of the same resilient material disposed between the gripping jaws and are fabricated during the molding process.
- FIG. 1 is a perspective view of a collet according to the present invention and particularly illustrates the inner diameter and outer diameter seals;
- FIG. 2 is a cross-sectional view of the present collet taken along the lines indicated in FIG. 1.
- FIG. 1a is a perspective view of the present collet with a double lip inner seal
- FIG. 2a is a cross-sectional view taken along the lines indicated in FIG. 1a.
- Collet 10 includes resilient material 22 for holding a plurality of gripping jaws 12 in a desired spaced relation relative to each other.
- resilient material 22 extends through perforations 32 within gripping jaws 12 so as to form essentially concentric rings of resilient material 22 through gripping jaws 12.
- Gripping jaws 12 are held by resilient material 22 in a desired longitudinally and angularly spaced relation about the longitudinal centerline axis of collet 10.
- Gripping jaws 12 include an exposed inner face 14 parallel to the centerline axis of collet 10. In this manner, the plurality of inner faces 14 define the inner diameter 16 of collet 10, as indicated in FIG. 1. The shaft or shank of the through-hole drill to be held by collet 10 is inserted through inner diameter 16, as is commonly understood in the art.
- Jaws 12 further include an angled exposed outer face 18 whereby the plurality of outer faces 18 define a conical outer surface 20 of collet 10.
- conical outer surface 20 matches a complimentary conical receiving surface of a collet holder (not shown).
- resilient material 22 is 10 generally flush with the outer exposed faces 18 of gripping jaws 12.
- resilient material 12 may be defined generally below the exposed faces 18.
- resilient material 22 also includes compression recesses 34 defined therein between each of the gripping jaws 12. Compression recesses 34 provide for compression of resilient material 22 when collet 10 is compressed within a collet holder. Compression recesses 34 may comprise a single recess defined in each interval of resilient material 22 as depicted in FIG. 1, or may comprise a series of holes, divets, or the like within resilient material 22.
- compression recesses 34 are particularly desired if the resilient material 22 is to be essentially flush with outer faces 18.
- compression recesses 34 are not a limitation to broader embodiments of the present invention.
- recesses 34 may not be necessary where resilient material 22 does not extend radially outward from the centerline axis of collet 10 flush with outer surfaces 18 of the gripping jaws.
- the necessity of compression recesses 34 is dependent upon the resiliency and/or volume of resilient material between the gripping jaws.
- Collet 10 further includes continuous outer diameter seal 24, as depicted in the figures.
- Outer seal 24 is formed integral with resilient material 22 and preferably is formed of the same material as resilient material 22. In this manner, outer seal 24 is molded integral with resilient material 22.
- outer seal 24 may comprise a material different from resilient material 22.
- outer seal 24 may comprise an O-ring or like structure of dissimilar material which is molded into resilient material 22.
- seal 24 be molded as an integral component of resilient material 22.
- seal 24 comprises a double lip seal 30, as indicated in FIG. 1.
- seal 24 may comprise a single lip 28.
- seal 24 may comprise a plurality of such lips.
- lips 28 and 30 extend radially beyond the outer faces 18 of gripping jaws 12. Seal 24 thus forms a continuous sealing ring about outer surface 20 of collet 10. It should be understood that the depiction of seal 24 in the figures is slightly exaggerated for ease of illustration. For example, applicant has determined that a sufficient height of lips 28 and 30 above outer face 18 of the jaws is generally 0.010 inches. If a double lip configuration is used, such as in FIG.
- a sufficient separation between the lips is generally 0.437 inches. It should be understood though that these measurements are in no way a limitation of the present invention.
- the height of lips 28 and 30 may vary. However, it is preferred to minimize the height of lips 28 and 30 above outer faces 18 so as not to interfere with the overall interface of outer faces 18 with the receiving conical surface of an associated collet holder.
- Collet 10 also preferably includes a continuous inner diameter seal 26 which is also formed integral with resilient material 22.
- inner diameter seal 26 also comprise a seal formed of the same material as resilient material 22 which is formed directly in the molding process of collet 10.
- inner seal 26 essentially forms an inner concentric ring of resilient material 22 extending radially inward beyond inner faces 14 of gripping jaws 12.
- Inner seal 26 may be formed essentially as an O-ring within inner diameter 16 of collet 10.
- inner seal 26 may be formed as a single lip or double lip configuration 26a, as with outer seal 24. However, for ease of manufacture, it is preferred to form seal 26 as illustrated in FIG. 1.
- inner seal 26 may comprise an O-ring or like device which is molded into resilient material 22.
- inner seal 26 and outer seal 24 in the figures with respect to the operative front and back ends of collet 10 is an example of a preferred embodiment of the invention. It should be understood though that, for example, outer seal 24 may be disposed at the extreme end of collet 10, or in the middle of collet 10. Likewise, inner seal 16 is preferably disposed at the extreme front end of collet 10 but, may be disposed virtually anywhere within inner diameter 16 of collet 10. Thus, the present invention is not limited to any particular location of the inner and outer diameter seals.
- collet 10 comprise only one of an inner diameter or an outer diameter seal.
- the outer diameter seal 24 may not be necessary.
- collet 10 would only comprise inner diameter seal 26.
- the present invention may only include an outer diameter seal 24.
- lips 28, 30 of outer diameter seal 24 depicted in FIG. 2 is an illustration of a preferred shape of the seals. However, it is within the scope of the invention to form lips 28 and 30 as a generally circular bead or ring, or other shape. The only requirement is that lips 28 and 30 extend radially beyond outer faces 18 of the gripping jaws so that when collet 10 is tightened within the collet holder, the lips compress and form a continuous sealing ring about the outer diameter surface of the collet. Likewise, as the gripping jaws are uniformly compressed radially inward, inner seal 26 compresses against the tool shank forming a continuous sealing ring therearound.
